The HF-2E variant is derived in part from the Hsiung Feng II anti-ship missile that equips its surface vessels, but it nearly quadruples the missile’s range from about 160 km to almost 600 km. The HF-2E is designed to be fired from land-based emplacements as well as ships, and GPS guidance is expected given its use in some modernized HF-2 missiles. The HF-2E’s range brings some of China’s southern ports within range of Taiwanese missile strikes against key staging areas, or even against retaliatory targets, if the PRC should invade.
